Thanks Julia! I'll be sure to try to add this to compat-drivers if the
upstream fb patch is not accepted. If it is accepted we would not need
this at all!

Nope, see that's the proactive strategy taken by the static inline and
hence the patch. compat would have a static inline for both cases, and
for the false case it'd be a no-op. If accepted upstream though then
we would not need any changes for this collateral evolution. However
*spotting* these collateral evolutions and giving you SmPL for them as
a proactive strategy might be good given that if these type of patches
are indeed welcomed upstream we'd then be able to address these as
secondary steps. If they are not accepted then indeed we'd use them to
backport that collateral evolution through both compat (adds the
static inlines) and compat-drivers (the SmPL).
